Here are some of the things we (wish we hadn't) learned from the book.

Trump didn't want to win

No, really. Wolff writes that, "His ultimate goal, after all, had never been to win. 'I can be the most famous man in the world,' he had told his aide Sam Nunberg at the outset of the race. His longtime friend Roger Ailes, the former head of Fox News, liked to say that if you want a career in television, first run for president. Now Trump, encouraged by Ailes, was floating rumors about a Trump network. It was a great future. He would come out of this campaign, Trump assured Ailes, with a far more powerful brand and untold opportunities."

Melania was in tears on election night, not of joy

Melania was reportedly, "assured by her husband that he wouldn’t become president, could return to inconspicuously lunching."

Wolff reveals that, "Shortly after 8 p.m. on Election Night, when the unexpected trend — Trump might actually win — seemed confirmed, Don Jr. told a friend that his father, or DJT, as he calls him, looked as if he had seen a ghost. Melania was in tears — and not of joy."

The Muslim Ban was put through to bait "Snowflakes"

Remember that Friday afternoon when Americans stormed airports all over the country to protest the Muslim Ban that has been rushed through? Apparently that was the intended effect.

According to the book the result of the Executive Order, "was an emotional outpouring of horror and indignation from liberal media, terror in immigrant communities, tumultuous protests at major airports, confusion throughout the government, and, in the White House, an inundation of opprobrium from friends and family. What have you done? You have to undo this! You’re finished before you even start!"

Wolff adds, "But Bannon was satisfied. He could not have hoped to draw a more vivid line between Trump’s America and that of liberals. Almost the entire White House staff demanded to know: Why did we do this on a Friday, when it would hit the airports hardest and bring out the most protesters?"'

'“Errr … that’s why,” said Bannon. “So the snowflakes would show up at the airports and riot.” That was the way to crush the liberals: Make them crazy and drag them to the left."

Trump really loves television, and McDonald's

You only need to read Trump's Twitter feed to see that he has the mind of child, whether it's bragging about the size of his nuclear button or repeatedly saying he's "the best" at {insert chosen subject}.

But what's going on behind closed doors is even more troubling. According to Wolff, “He ­reprimanded the housekeeping staff for picking up his shirt from the floor: “If my shirt is on the floor, it’s because I want it on the floor.” Then he imposed a set of new rules: Nobody touch anything, especially not his toothbrush. (He had a longtime fear of being poisoned, one reason why he liked to eat at McDonald’s — nobody knew he was coming and the food was safely pre-made.) Also, he would let housekeeping know when he wanted his sheets done, and he would strip his own bed.”

Ivanka wants to be the first female president

If you think Don Jr is the one being groomed for power, think again. According to the book, "Balancing risk against reward, both Jared and Ivanka decided to accept roles in the West Wing over the advice of almost everyone they knew. It was a joint decision by the couple, and, in some sense, a joint job. Between themselves, the two had made an earnest deal: If sometime in the future the opportunity arose, she’d be the one to run for president. The first woman president, Ivanka entertained, would not be Hillary Clinton; it would be Ivanka Trump."

In another tease of the gems this book has in store, Katy Tur of NBC News has shared a page which reveals the tactics Trump reportedly used to use to seduce his friend's wives, a goal he's reportedly obsessed with.
